Bio-oil derived hydroprocessed renewable jet HRJ fuels are alternative fuels that are being evaluated for use in United States Air Force USAF aircraft and support equipment and vehicles SEV. As with any new weapons system or other type of potential fire threat, the fire protection safety risk to the first responder must be established. This program was designed to determine if Military Specification MIL-F-24385F MIL-SPEC Aqueous Film Forming Foam AFFF has the capability of extinguishing HRJ fuel fires and HRJJP-8 blended fuel fires. The assessment included extinguishment effectiveness, extinguishment time, and burn-back time. Heat flux was also measured for six-foot pan fires with HRJ and synthetic alternative fuels and fuel blends. Jet fuels evaluated in this program were conventional JP-8 fuel specified by MIL-DTL-83133F, two HRJ fuels produced by UOP LLC, a Synthetic Paraffinic Kerosene SPK fuel produced by Syntroleum Corporation S-8 and a synthetic fuel produced by Shell FT-IPK.
